Hello everyone.
I have a Ultimaker 3 extended, and something really weird happened. I started a print, which worked normal for 3 hours, then I left home and came back in 6 hours, and it seemed like the material stopped extruding hours ago and didn't print much further after the three hours. The PVA extruder looks burnt, and the PLA had material all over it like- completely covered. I wanted to check if the material got stuck because of bad temperature, however I knew that I've set it up right, and then when I unloaded the materials I saw that they we're BOTH bent in and a little broken, right where their end was getting into the feeder (I'll attach a picture.) I really can't figure out how and why this happened, especially how it happened to both of the materials...
Does anyone possibly know the cause?
